System and method for providing a communal jackpot

ABSTRACT

A system for providing a communal jackpot includes a plurality of gaming machines. Each gaming machine provides an individual game of chance to a player wagering at each respective gaming machine. A communal jackpot controller is in communication with each of the gaming machines. The communal jackpot controller provides a communal jackpot game to the players wagering at each gaming machine and awards the communal jackpot to a plurality of players according to predetermined eligibility criterion when triggered.

FIELD OF THE INVENTION

The present invention relates to gaming machines and in particular to systems and methods for providing communal jackpots to players playing gaming machines and will be described with reference to this application. However, it will be appreciated that the invention is not limited to this particular field of use.

BACKGROUND OF THE INVENTION

In this specification unless the contrary is expressly stated, where a document, act or item of knowledge is referred to or discussed, this reference or discussion is not an admission that the document, act or item of knowledge or any combination thereof was at the priority date, publicly available, known to the public, part of common general knowledge; or known to be relevant to an attempt to solve any problem with which this specification is concerned.

Slot machines were initially stand alone wagering machines in which a fixed percentage of the wagers was returned to the players over a period of time. Jackpots are a desirable feature as far as the operator of the machines is concerned as they are popular with players and can provide large pool sizes compared with the standard prizes. Jackpots are available on individual slot machines in which the jackpot is taken from the amount of wagers on the machine. This lowers the average non-jackpot return of the machine as the jackpot is included in the average return. However, for slot machine players, the provision of a jackpot feature is considered to be a desirable feature.

Communal contribution jackpots are also available on slot machines where a plurality of gaming machines contribute revenue to a jackpot pool. In this way electronic slot machines can be linked into large groups and large jackpots can be accumulated. Communal contribution jackpots on slot machines usually operate by diverting a percentage of each wager into the jackpot pool, which has the effect of decreasing the prize pool for each individual slot machine available for the non-jackpot prizes. These jackpot pools can be substantially larger than those available on individual machines, and this increases their popularity with players. In such jackpot games, a player contributes to the jackpot pool whether or not the player wishes to participate in the jackpot and the jackpot is only awarded to a single player when triggered.

Mystery jackpots usually set a lower and an upper limit within which the jackpot must be won. In known slot machine jackpot systems, a pooled jackpot is funded by taking a percentage of each wager on each linked machine to build up the jackpot pool.

A disadvantage of the prior art is that players may perceive that the odds of winning the communal contribution jackpot are small so they may avoid playing machines connected to the communal contribution jackpot.

PREFERRED EMBODIMENT OF THE INVENTION

The preferred embodiment of the invention discloses a system for providing a communal jackpot in a gaming venue and/or across multiple gaming venues. The venues may be within one city, state or country or may be, in some instances, be provided across countries. The system includes a plurality of gaming machines, each gaming machine providing an individual game of chance to a player wagering at each respective gaming machine. The gaming machines may provide the same individual game to players or each machine may provide a different game to the players. These games are individual in that the result or outcome provided on one machine is independent of the result or outcome provided on another machine. A communal jackpot controller is in communication with each of the gaming machines via a local area network (LAN), Wide Area Network (WAN), the Internet, VPN or any other suitable communication network. The communal jackpot controller provides a communal jackpot game to the players wagering at each gaming machine, the communal jackpot controller awarding the communal jackpot to a plurality of players according to predetermined eligibility criterion when triggered.

The communal jackpot has an award or prize value that is typically prominently displayed to the players. This creates excitement and draws people to the gaming machines connected to the communal jackpot. Upon placing a wager on one of the gaming machines, a percentage of each player's wager on the individual game of chance is allocated to the value of the communal jackpot. This percentage is typically predetermined by the gaming venue and can be amended as required. For example, if the percentage is set at 5% and a player wagers $1 on an individual game, then an amount of $0.05 will be allocated towards the communal jackpot prize. The communal jackpot prize is then incremented by $0.05.

The communal jackpot is triggered when the value of the communal jackpot crosses a threshold trigger value. The trigger threshold value is typically random and is predetermined by the communal jackpot controller when the controller is initialised or when reset after a communal jackpot has been awarded. In some embodiments the trigger threshold is predetermined by the venue, however, this is less preferred. The trigger threshold value is typically set between a minimum jackpot limit and a maximum jackpot limit. This ensures that the communal jackpot amount does not start at $0 where a player would not be inclined to participate in the communal jackpot game. A maximum limit is also set so as to ensure that the communal jackpot is won within an estimated time period with the venue setting the upper limit of the prize they believe is reasonable to pay. The minimum and maximum thresholds are typically set by the gaming venue and can be changed when required preferably at the start of a new communal jackpot game. The display of the minimum and maximum thresholds also creates player excitement especially in the event that the jackpot value approaches the maximum threshold as players understand that the jackpot must be won at or before the jackpot value reaches the maximum threshold.

Each of the players wagering on an individual gaming machine connected to the jackpot controller is eligible to receive a portion of the communal jackpot when triggered according to one or more of the following criteria: the player having an active wager on the individual game provided at their respective gaming machine; the value of the player's wager on the individual game being above a minimum eligibility threshold; the physical location of the gaming machine; the player being enrolled in a venue loyalty scheme; the average wager of the gamer on the individual game during the course of a predetermine time period; player statistics associated with the loyalty scheme; the player electing to place an additional ante bet; a random selection of a plurality of players; the player placing a wager on the individual game where that wager is higher than the average wager of a predetermine percentage of other players' wagers; the player wagering the maximum wager available on the individual game; the magnitude of a player's wager relative to other players' wagers'; or any other suitable criteria or criterion.

That is, the gaming venue can specify a plurality if eligibility criteria for allowing a player wagering at a gaming machine to win a portion of the communal jackpot prize when triggered. The particular criteria can be determined by the venue and may be set to ensure the most enjoyment by players and to create an environment where everyone wins. This ensures that some players are not disappointed when a jackpot is triggered and they are not the winner as when a jackpot is triggered in this embodiment all eligible players win.

In one embodiment the player whose wager causes the communal jackpot to trigger and be awarded receives an equal amount of the communal jackpot prize along with all other eligible players. In another embodiment a venue can reward that player with a larger portion of the jackpot prize with the other eligible players receiving equal portions of the remaining prize.

In these embodiments, the percentage of each player's wager on the individual game of chance that is allocated to the value of the communal jackpot is added individually and the player whose contribution causes the value of the communal jackpot to cross the threshold trigger value is awarded a predetermined percentage of the communal jackpot.

The preferred percentage provided to the player whose wager triggered the jackpot is 80%, however, the predetermine percentage can be selected from one of: 10%; 20%; 30%; 40%; 50%; 60%; 70%; 80%; or 90% or indeed any percentage between 1% and 100%. The remaining value of the communal jackpot is awarded to the remaining eligible players according to predetermined criteria. In the preferred embodiment the remaining value of the communal jackpot is awarded to the remaining eligible players in equal portions however in some embodiments the remaining prize is not allocated in equal portions and one or more of the eligibility criteria may apply to determine which player receives which portion. For example, the player that triggered the jackpot may be allocated 80% of the jackpot with the eligible player who placed the highest wager on the individual game in progress or immediately before the triggering of the jackpot receiving 10% of the prize. The remaining eligible players may then be awarded equal portions of the remaining 10% of the prize. Alternatively the players who had the next highest wager would receive 5% of the prize with the remaining eligible players equally being awarded the remaining 5%. Alternatively the remaining portions of the jackpot are awarded progressively according to the criteria chosen until the entire jackpot prize is awarded. This may mean some otherwise eligible players are not awarded any of the prize as they did not rank sufficiently in the awards process. The particular percentages awarded to each player can be determined by the venue according to the criteria most advantageous for the venue or players.

The preferred embodiment of the invention also discloses a method for providing a communal jackpot. The method includes the steps of: providing a plurality of gaming machines, each gaming machine providing an individual game of chance to a player wagering at each respective gaming machine. The next step provides a communal jackpot controller in communication with each of the gaming machines, the communal jackpot controller providing a communal jackpot game to the players wagering at each gaming machine, the communal jackpot controller awarding the communal jackpot to a plurality of players according to predetermined eligibility criterion when triggered.

The preferred embodiment of the invention provides a system and method for triggering a feature or Mystery Jackpot in a plurality of EGMs. The EGMs may be supplied by the same or different manufacturers and may have the same of different games thereon.

The preferred embodiment of the invention has been developed primarily for awarding a jackpot prize of monetary value, however, non monetary prizes can also be awarded. In the case of non monetary prizes, a plurality of prizes is preferably awarded to a plurality of players. Each non monetary prize may have a different value associated with it and the prizes may be awarded randomly or preferentially according to the criteria specified above. Non monetary prizes include televisions, laptop computers, Ipods, Iphones, mobile phones and the like.

The preferred embodiment of the invention provides a communal jackpot system that can add a feature game or jackpot to a plurality of machines from one or more EGM manufacturers. Typically in the prior art, external or internal electronic devices (such as Jackpot controllers) connected to electronic gaming machines allowed venues to award different types of jackpot prizes to players. However, these jackpot prizes were restricted to one particular EGM type from a single manufacturer. As such when a venue such as a Casino and/or Club wanted to change or add a new jackpot game (for example for seasonal events and the like) they needed to request that the specific EGM manufacturer add the feature to their gaming machines. This involves added cost and time. EGM manufacturers also only add feature games to the gaming machines they manufacture. Accordingly, the community jackpot system of the preferred embodiment is advantageous as it can provide a plurality of EGMs from different manufacturers with a common jackpot game and system.

A standard mystery jackpot game according to the preferred embodiment involves a secret random jackpot prize being won by a electronic gaming machine that is being played. Each EGM approved to be connected to the mystery jackpot system contributes a set percentage of its turnover to the prize pool, the value of which is shown on the display. The jackpot is won between two set limits, the minimum and maximum prize, when the player contributing the last increment matches the predetermined random prize.

The jackpot system of the preferred embodiment randomly selects the maximum trigger threshold (from within predetermined thresholds) after each time the jackpot is triggered. For example, if the predetermined approved thresholds for a mini jackpot is $25 (minimum threshold) to $100 (maximum threshold) then the controller randomly selects a figure between these two numbers to act as the trigger value. If the trigger value is, say, selected as $72 then the next jackpot will be won when the value of the jackpot crosses over the trigger value of $72. Each time a player wagers on a linked EGM then a percentage of their wager is allocated to the jackpot value. For example, if the player contribution is $1.13 and the jackpot minimum amount is $25 then after that wager the jackpot amount will be incremented by $1.13 to $26.13.

In some embodiments the controller randomly selects the upper threshold and trigger values so that the upper threshold can be seen to change from the perspective of the player. As would be understood the trigger value would not be revealed to the players. In the example described below, the maximum threshold value selected was $76. It would be understood that the jackpot value would not reach the value of $76 but would be triggered at the trigger value selected in this instance of $72.

FIGS. 2 and 3 are images of displays that are shown to players. The displays can be on a gaming machine display or can be shown on a separate information display on a large screen TV or the like. Each image has two layers, the overlay and the background. The background may be a still picture or a movie clip according to the preference of the venue. The overlay displays information on the jackpots to the players. As would be understood, the jackpot controller can provide a plurality of community jackpot games to the players. The preferred embodiment provides a grand jackpot, a major jackpot, a minor jackpot and a mini jackpot. It would be understood that the number of jackpots and the features of each jackpot can be selected by the venues and can be amended as desired.

FIG. 2 shows an overlay of a minor jackpot. The background 201 can be a still image or movie clip. The overlay picture has two parts, 202 and 203 which display information to the viewer/player. In this instance the overlay 203 informs the player that the next minor jackpot will be won before the jackpot value reaches $223. The overlay 202 informs the viewer that the current minor jackpot value is $200.85.

FIG. 3 shows an overlay 301 that includes information on four jackpot types. A grand, major, minor and mini jackpot. The current value of each jackpot is shown along with the value of the jackpot by which the jackpot must be awarded. As would be understood this provides excitement to players especially in instances where the current jackpot value is close to the maximum jackpot value at which the prize must be awarded. As would be understood, the overlay is placed on top of the background image and is used to display the numeric information about the jackpot. The display can cycle between a single level display and a multi level display as required. Alternatively a separate display can be provided for each jackpot.

FIG. 4 shows an embodiment of the invention where electronic gaming machines EGM1, EGM2 and EGM 3 are connected to a mystery jackpot system. All the active, (being communicating and playing) EGMs connected to the mystery jackpot system contribute a set percentage of the EGM s turnover to the prize pool on the display. The jackpot must be won between two set minimum and maximum limits and the system awards a mystery jackpot to a single EGM either EGM 1 or EGM 2 or EGM 3 based on certain conditions.

FIG. 5 shows a more preferred embodiment of the invention where the jackpots triggered are awarded to two or more active EGMS. The Figure shows a jackpot system where players playing an EGM share in the advertised prize pool of a particular jackpot level instead of a single winner. The preferred embodiment of the invention involves awarding multiple EGMs with a predetermined communal payment method. The method of the communal payment can be decided from a number of predetermined scenarios. Different methods can be implemented to achieve awarding the mystery jackpot to a plurality of EGMs. Some of the most preferred methods are described below. All the EGMs connected to the mystery jackpot systems satisfying certain conditions such as actively playing/online at the time of mystery jackpot hit can are awarded a portion of the jackpot.

Selecting EGM and EGM groups can be based on, but not limited to, the following criteria as well as the criteria mentioned above:

-   -   Banks—EGMs grouped together in “banks” in certain areas of the         venue.     -   Denomination—EGMs are awarded if their denomination matches the         triggered winner (for example, 1 c, 2 c, 5 c, 10 c, 50 c, $1, $2         and so on according to the number of denominations provided by         the venue).     -   Odd/Even EGM house numbers     -   Inter venue group, venue (Casino/Club) choice.     -   Random selection of all or some of the active EGMs.

FIG. 5 shows a preferred mystery jackpot award system. EGMs EGM 1, EGM 2 and EGM 3 are connected to a mystery jackpot system which includes a jackpot controller. All the active (being communicating/playing) EGMs connected to the mystery jackpot system contribute a set percentage of the EGMs turnover to the prize pool. The jackpot is triggered and won when the value crosses the trigger threshold which is randomly set between the minimum and maximum award limits. The jackpot prize is awarded to one or more of the EGMs according to the preferred selection criterion or criteria. That is, all the EGMs, or a plurality of EGM1, EGM2 and EGM3 can be awarded a portion of the jackpot prize.

The preferred embodiment of the invention provides a jackpot system for allowing a jackpot to be awarded to EGMs used at a plurality of venues. The jackpot controller is in communication with all the EGMs across all the venues and when a jackpot is triggered the controller selects different EGMs across the different venues to be awarded a portion of the jackpot prize. The EGMs criteria for choosing which EGMs are eligible to be awarded a portion of the prize is based on certain conditions in each venue or a global set of criteria. While examples given in the preferred embodiment use two venues the system can be extended to any number of venues.

FIG. 6 shows a system for a inter venue community jackpot. The system shown in FIG. 6 provides a mystery jackpot system for providing a jackpot across a plurality of venues and allows a triggered jackpot to be awarded to EGMs across the venues. For example, a jackpot may be triggered at one venue and EGMs at that venue and additional venues may be eligible to be awarded a portion of the jackpot prize. The awarding of the jackpot prize to different EGMs in different venues is determined on predetermined conditions at each venue. Alternatively a global set of criteria can be used to determine which EGMs are eligible to receive a portion of the jackpot.

The system shown in FIG. 6 has two venues. Each venue includes a plurality of EGMs connected to the jackpot controller. The first venue has 8 EGMs denoted by V11, V13, V15, V17, V19, V111, V113, V115. The second venue also has 8 EGMs denoted by V20, V22, V24, V26, V28, V230, V232, V234.

In various implementations, a jackpot that is triggered is awarded to a plurality of EGMs from each venue. In one example, EGMs V15, V17, V234, V20, V26 are eligible to be awarded a portion of the triggered jackpot. This eligibility may be based on any of the criteria mentioned above such as the banks in which the machine is physically placed, the theme of the game provided, denomination of the machine, odd or even EGM number, inter venue group, or may be based on the choice of the Venue (which may be a casino or club).

In one embodiment, a themed communal jackpot system is provided. The theme is based on the sporting event the “State of Origin” which is played between two teams of players, one from Queensland and one from New South Wales. The theme is named the “State of Origin Community Jackpot”. In this system two banks (or rows) of EGMs are provided. One bank has a Queensland theme and the other has a New South Wales theme. The theme may include a game that is tailored towards the particular team and row in which the EGM is placed and may include tailored graphics, colours, sounds and the like. Alternatively the game on each EGM may remain unchanged and the decoration around the EGM is simply chosen according to the desired theme. This embodiment may be a single game community jackpot or a multiple venue community jackpot. In the multiple venue embodiment a venue or venues in New South Wales are provided with EGMs with the New South Wales theme and a venue or venues in Queensland are provided with EGMs with the Queensland theme. As would be understood, the system is not limited to this theme and the particular teams mentioned herein and any suitable theme, whether sporting or otherwise can be used.

In this embodiment, when a player playing an EGM in one of the banks triggers a community jackpot level all players on his or her bank that are actively playing an EGM receive a share of the jackpot prize.

For example, take the case of a four level jackpot system connected to 20 EGMs. The EGMs are separated into two banks (physical groups) of 10 EGMs on each. The signage above bank 1 depicts maroon colours and includes themed signage of the Queensland side. Bank 2 depicts blue colours and includes is themed signage of the New South Wales side.

The system includes four jackpot levels. Three of the jackpot levels being levels 2, 3 and 4 operate a standard mystery game that is awarded to a single EGM only, being the EGM that triggered the jackpot. The level 1 jackpot operates as a community jackpot and is shared between the eligible EGMs playing on the same bank as the EGM that triggered the jackpot.

Say there are currently five players actively playing on the Queensland bank. Say also that there are four players actively playing on the NSW bank. The current prize pool of the level 1 community jackpot is $6,000.

If the level 1 community jackpot is triggered by one of the EGMs on the New South Wales bank then the jackpot amount of $6,000 will be awarded to those eligible EGMs on the New South Wales bank. Since there are four active and eligible players on the New South Wales bank in this embodiment the jackpot prize will be shared equally among each of the four EGMs. That is, the four players actively playing at each of the EGMs on the New South Wales bank that triggered the jackpot are each awarded $1,500 from the jackpot prize pool ($6,000 divided by four players). In other embodiments the player at the EGM that triggered the jackpot would be awarded 50% of the jackpot ($3,000) and the remaining three players would share the remaining 50% equally. That is, they would receive $1,000 each. It would be understood that the division of the jackpot can be determined according to the criteria mentioned above.

In some jurisdictions players are limited to receive a certain payment by automatic transfer to the EGM. In these jurisdictions the venue may advertise the full jackpot amount in the knowledge that the jackpot amount will be below the threshold. As such, this may be advantageous as a larger jackpot amount than will be awarded to any one player can be advertised.

In another embodiment, a player at the Queensland bank triggers the communal jackpot. All players actively playing in the Queensland bank receive a share of the jackpot prize however the player at the EGM that triggered the jackpot received 80% of the prize and the remaining players share the other 20% equally. If the jackpot were $6,000 then the player that triggered the jackpot would receive $4,800 and each of the other fours players at the Queensland bank (assuming five active players in total) would receive an equal share of the remaining $1,200 being $300.

In another embodiment a 2, 3 or 4 level jackpot system is connected to 20 EGMs. All available levels of jackpot act as a communal jackpot where the jackpot prize is shared among the active and eligible EGM's.

Say there are five players actively playing on the bank. The level 3 community jackpot is triggered by one EGM on the bank. The current prize pool of the level 3 community jackpot is $1000. The triggering EGM receives a prize of $800 (80% of the prize pool) and the four other active machines share the remaining 20% of the prize being $50 each.

In one embodiment, as players on gaming machines participate in a first game provided at each gaming machine they contribute to the prize pool of a jackpot game. The jackpot controller is enabled for up to four simultaneous jackpot games. Each game has a different jackpot level and is enabled to be of one of two types: a standard game or an enhanced game.

The standard game involves a secret random monetary prize, called a jackpot which occurs between published upper and lower limits. The jackpot controller randomly determines a jackpot win value between the upper and lower limits. This value is not revealed while the prize pool is being contributed. As games are played on each gaming machine a percentage of the gaming machine turnover is contributed to the prize pool. When the prize pool reaches the randomly selected win value the jackpot is won. The gaming machine or in the case of a communal jackpot, the group of gaming machines that contributed the win amount to the prize pool is awarded the jackpot. After the jackpot has been won the prize pool is reset to the published lower limit.

In an enhanced game, the win value is randomly selected in the same manner as the standard game. However a second random value is selected and caused to be displayed on the jackpot displays, revealing it to the players while the prize pool is being contributed. In the preferred embodiment of the enhanced random game the second random number is generated to fall between the randomly selected win value and the published upper limit. When revealed to the players it is indicated that the jackpot must be won “under this limit”. This seemingly reveals narrower odds of winning the jackpot, but does not affect the payout percentage or turnover statistics, which are the same as for the standard random game.

Displays according to the enhanced game can be seen in FIGS. 2 and 3 where the second random value is shown to players as the value by when the jackpot must be triggered.

In another embodiment of the enhanced random game the second random number is generated to fall between the published lower limit and the randomly generated win value and caused to be displayed to the players on the jackpot displays. This reveals a higher initial jackpot value to the players, encouraging them to participate in the new game.

For the standard random game the average jackpot win amount is calculated by using the following formula:

average win=(maximum−start up)/2+start up

The probability of a jackpot hit on the next increment is:

1 in P=(maximum−current)×100.

For the preferred embodiment of the enhanced random game the average jackpot win amount is calculated using the following formula:

average win=(maximum−start up)/2+start up

The average reveal amount is equal to the following formula:

average reveal=(maximum−average win)/2+average win.

The probability of a jackpot hit on the next increment is:

1 in P=(reveal−current)×100.

As can be seen from the above disclosure, the preferred embodiment of the invention provides a useful system for providing a communal jackpot.

Any commercial processor may be used to implement the embodiments of the invention either as a single processor, serial or parallel set of processors in the system.
